but if components are upgraded accordingly, then there shuldn't be an issue. It also depends on how the car is driven too. If a car is constantly being pushed to its limits, then yeah expect something to go bang eventually. But if this car is driven regularly day in day out, and put through its paces every so often, then i say it will hold up as good as stock.

I'm guessing that this will be daily driven, and see higher rpms every now and again?
